git commit -m "feat(core.latex.renderer): modularize renderer & add snacks.nvim integration

- Refactored 'core.latex.renderer' to decouple image generation from image display, addressing feedback regarding modularity.
- Restored original 'latex' + 'dvipng' generation logic and 'dpi' configuration to ensure backward compatibility and image quality control.
- Added 'core.integrations.snacks' as a new, optional rendering backend.
- Implemented the standard renderer interface (new_image, render, clear) for Snacks.
- Added support for multi-line '@math' blocks and fixed cursor concealment logic.
- Users can now switch renderers via the 'renderer' config option."
